WILLIAM HENRY BURNS, OF NAPERVILLE, ILLINOIS.

ELECTRIC INSOLE.

Specification of Letters Patent.

Patented June 3o, 1908.

Application filed July 11, 1907. Serial No. 383,351.

To4 all whom it may concern:

Be it known that I, WILLIAM HENRY BURNS, citizen of the United States, residing at Naperville, Illinois, have invented certain new and useful Improvements in Electric Insoles, of which the following is a specification.

My invention relates to improvements in electric soles and has for its object to provide an inner sole for boots and shoes which will produce more effective circulation of an electric current than those heretofore roduced of which I am aware; and which wi l occupy a minimum amount of space, and which will not re uire any special pockets or recesses, and wil not tend to produce any uneven places on the interior of the shoe where the sole of the foot rests.

'Vith these and possibly other objects in view the invention includes the novel features of construction and arrangement of arts hereinafter described and particularly set forth in the appended claims.

An embodiment of the invention is illustrated in the accompanying drawing, in which,

Figure l is a plan view, and Fig. 2 a side elevation partly in section. Fig. 3 is a plan view of the plates separated.

Referring by reference characters to this drawing, the 4numeral 4 designates the improved sole which is composed of two plates 5 and 6, the one (5) of copper and the other (6) of zinc. These are formed, each of a single piece of material with a continuous rim and alternating bars and spaces as clearly shown in Fig. 3.

The bars and spaces of both plates are arran ed at an ang e or inclination to the line of t e foot, and are arranged so that when one of the plates is placed upon the other the bars 5 of the plate 5 will come opposite the spaces 6b of the other plate and vice versa, the bars 6l1 opposite the spaces 5b.

The two plates are secured together by line of copper rivets extending around the outside, as shown at 7. By this construction and arrangement I provide an insole in a galvanic couple extending over the entire surface of the sole of the foot and without any uneven parts, and without the necessity of providing any recesses or the like in the sole ofthe boot or shoe.

I may sometimes fmd it desirable to provide a layer of insulating material, such as rubber, on the under side of the galvanic couple as indicated at 8.

It will be understood that the foot of the wearer contacts with the upper plate and protrudes between the space therein into contact with the lower plate also thereby an external circuit is produced through the foot of the wearer. The perspiration or moisture from the foot of the wearer between the juncture of the two metals forms an electrolyte which produces an electric current thus malrinO an internal circuit in the cell.

aving thus described my invention, what I claim is:

An electric insole comprising a pair of super osed metallic plates each of which has a ternating bars and spaces, one plate being in alinement with the spaces of the other so that the foot of the wearer contacts upon the bars of the upper plate and protrudes through the spaces therein into contact with the bars of the lower plate.

In testimony whereof, I aflix my signature in presence of two witnesses.

WILLIAM HENRY BURNS.
